Experimental Overwatch Balance Changes Target Baptiste, D.Va

The Overwatch Experimental patch notes for April15, 2021 are now live and they include balance changes to many heroes.
While the Overwatch Experimental changes are not a reflection of the actual servers, it is where developers playtest and decide which changes balance characters effectively and which ones are nerfs or buffs too extreme to reach live servers. According to the official patch notes, Baptiste is the hero who has had the most changes this patch.
Walk in harmony.
